Question #7e0de Chemistry Solutions Molarity 1 Answer Michael Apr 22, 2015 93.12g c=n/v Where: c = concentration v =volume n = no. moles So: n=cv n= 0.5xx2.5 = 1.25 M_r[KCl]=(39+35.5)=74.5 So 1 mole weighs 74.5g So 1.25 mol weighs 1.25xx74.5 = 93.12"g" (Approx A_r values used) Answer link Related questions what is the molarity of 20.0 ml of a KCl solution that reacts completely with 30.0 ml of a 0.400...
